How to set an item stacking rule on task executer?

I would like to have my task executer stack items like how queue does. Each layer stacks nine item, and they are stacked from first layer upwards. Here's what i write in trigger function On Load:

treenode item = param(1);

treenode current = ownerobject(c);

treenode station = param(2);
{

treenode involved = item;

double x = xloc(item)+.59;

double y = yloc(item)+.07;

double z = zloc(item)-1.2;

setloc(involved, x, y, z);

}

and it stacks items in a tower. How can i revise the code? Thank you in advance!

Software Version:

FlexSim 22.0.16

You need to refer to the rank and size of the item in your stacking logic. You can do it in the Visual>Set Location option of the OnLoad trigger.

This example stacks items in 3 x 3 layers:

Here's another version where you can just specify the x and y dimensions (and offset position) using the labels on the task executer:

OnLoadStackingLogic2.fsm

In this case the expressions are a little more complex:

(note: strictly speaking I should have used 'involved' rather than 'item')

@Briankuo

You can solve your stacking method using item property changed.

Use container item like Tote or Pallet not basic item box.

You can add new a container item in Flowitem Bin and change the new pallet visual to box visual.

You do not need to use setloc() script code.
